A coffee vending machine hire is far more affordable than an outright purchase. If you are intrigued with the concept but are not quite ready to make a massive investment, then this path is the more sensible choice.
By renting a machine, you can test its viability in your office, your station, or your store. See how many people use it and get their feedback about the experience. You can make improvements on the product offerings based on the reviews.
Renting also means that the company is still the owner and it is in their best interest to keep the machines going. If there are any issues, you can just call them and they will fix the problem for you.
You can begin the business right away given the small rental fees. Get your stock of the ingredients and start brewing.
